Well the whole "id software is still in business" does not make any sense because Wolfestein 3D has been made abandonware. But thanks anyways.

Where did you get that idea? It's still on sale and supported, therefore it's not abandonware. Neither is Doom. Something counts as abandonware if you can't buy it. And "abandonware" as a legal term doesn't even exist, so even if it is abandonware, downloading it is still piracy.

Can't buy it may include 2nd hand... as in completely unavailable except via dubious means.Some (most) would argue if the company is still in business and their software can be bought 2nd hand, then they have not abandoned it. Even if they have pulled the patches for it.

Also, it would be wise to not confuse publishers and primary developers in this regard. (Not that anyone has, it's just general advice).
